MEANS FOR SEALING WALL AND FLOOR JOINTS, ETC.

Application iedseptember 12, 1924. semi Nd. 737,233.

My invention is concerned with the provision of improved means for sealing the jointsv between walls and floors, etc., and is vparticularly concerned with the provision of means for sealing the joints between the floors and inside walls of railway refrigerator cars.

Nowadays in shipping certain classes of perishable produce it has becomevcustomary l0 to place ice in the main compartment of the car, that is, between the bulk heads, with the result that water collects upon the car floor and tends to seep under the interior walls of the car and to cause disintegration of inaccessible woodwork and the heat insulating material which is frequently placed between the inner and outer walls of refrigerator cars.

My invention contemplates the provision '30 of a seal which will adapt itself to irregularities in the contiguous portionsof a floor and a wall and produce a water-tight joint between them, which easily may be applied and which is relatively inexpensive;

3 In the accompanying drawings illustrating` a preferred embodiment of my invention Figure 1 is a fragmentary section of a railway refrigerator car having a joint sealed infaccordance with my invention;

3f Figure 2 is a perspective view of the preferred form of rubber sealing stripwhich I employ in forming my improved seal;

Figure 3 is a top plan view of the strip; Figure 4 is a sectional'view of the contiguous portions of the floorl and wall and Vthe elements of the'seal as they appear prior to the completion of the joint, and l Figure 5 is a similar view illustrating the completed joint. 1 Y

Similar characters of reference refer to similar parts throughout the several views.

In Figure 1 reference numeral 6 indicates the floor, and the numerals 7, 8V and 9 the inner, intermediate and outer' walls of a refrigerator car of conventional construction. The spaces between the walls may be dead air spaces or maybe filled, or partially filled,

with heat insulating material indicated at 10..

The inner wall 7 is preferably formed. of horizontally disposed lumber provided with the usual cooperating` tongues and grooves. It is perhaps not essential that all of the boards of the wall 7 be provided with tongues and grooves, but it is desirable that the lowermost board of this Wall be provided with a longitudinal groove 11 in theedge Y Aboard of wall '7, and, if desired, may be slightlytapered upwardly in itsvertical'section, the upper edge of the web being somewhat narrower than the groove11, and the lower portion ofthe web being slightly greater than the width of the groove 11.

The iianges 13 are .preferably of such width that when they are compressed as illustrated in Figure 5, their free longitudinal edges lie substantially flush with the sides of the wall board which they underlie. with a plurality of apertures 15 disposed in parallel rows, the apertures of one row being staggered with respect to those of the other row.

In making the preferred seal embodying my invention, the web 12of the rubber sealing strip is fitted into the groove 11 of the lowermost wall board, and-the "latter is brought down to the position shown in F ig' ure 4 with an Ainitially plastic sealing compound 16 (preferably including.. asphalt as one of its constituents) in the space between the floor and the walls of the grooveV 14. The plastic sealing joint either may be placed I prefer to provide each iange l?) upon the floor along a line directly under the l position yto be occupied by thelowermost .wall board,v or may .be placed in the groove 14 before the said wall board and the sealing strip are brought to the position shown in Figure 4. y y

With the several elements occupying the position shown in Figure 3, and with the compounds `16 still plastic, the lowermost wall board'is forced down toward the ioor substantially tov flatten out the sealing strip flanges 13 under the margins of the groove 11, as illustrated ,in Figure 4. When this operation has been accomplished, the plastic sealing material iiows upwardly through the apertures 15 to overlie, as well as to underlie, the flanges'of the sealing strip. The said wall board is then nailed or otherwise secured in` position, and the composition 16 hardens, or partially hardens, as the case may be.

I contemplate that in some cases I may dispense with the sealing composition 16 and that the cross section of the sealing strip may be varied. Thus do not limit myself to the specific construction and arrangement of parts lieieinclaiined and described.

Vliat liclaim is new and desire to seure by Letters Patent, is:

l. The combination of afloor and a wall board to be fitted thereto, said wall board having a longitudinal groove in the edge thereof adjacent said floor, with a deformable sealing strip having a web adapted to be received ,in said groove and flanges diverging from said web forming groove in the bottom of vsaid strip, and unstable plastic sealing compound in said latter groove, whereby said sealing compound is distributed between said floor and strip when said wall board is pressed against fioor.

2. The combination of a fiooi and a wall board to be fitted thereto, said wall board having a longitudinal groove inthe edge thereof adjacent said floor, with a r 'lient rubber sealing strip having a web adapted vto be received in said groove and flanges' diverging rfrom said web forming groove in the bottom of said strip, and initially plastic sealing compound, including asphalt as a constituent in said latter groove, whereby said sealing Compound is distributed be` tween said floor and strip when :aid wall board is pressed against -said floor.

3. The combination of a floor anda wall board to be tted thereto, said wall board having a longitudinal groove in the edge thereof adjacentL said floor, with a deformable sealing strip having a web adapted to be received invsaid groove-and flanges divergingfrom saidweb-forming a groove in the bottom of said strip, said flanges havinga plurality Aof openings therethrouglnnnd unstable plastic sealing compound in saidv latter groove, whereby said sealing coin-v pound is distributed between said floor and stripiand passing through said openings is verging from said web forming a groove in i the bottom of said strip,-said flanges having a plurality of openings therethrough, and initially plastic sealing'compound, including asphalt a constituent, in said latter groove, whereby said sealing compound is distributed between said `Hoor and strip and passing through said openings is also distributed between said flanges and wall board when said wall board is pressed' against said floor.` i i 5. rEhe combination of a floor and a Wall bo i, to be fitted thereto, said wall yboard having a longitudinal. groove inrvthe edge thereof adjacent said `lioor, with a deforniable sealing strip having a web adapted to be received in said groove, a lateral .flange on said web and a groove in thebottom of said strip, and unstable plastic sealing compound in said latter groove, whereby saidY sealing compound is distributed between if. d 'floor and strip when 'said wall-board is presepi said floor,V l

6. The combination of a floor anda wall board to befitted thereto, said wall board having a longitudinalrgroove in the edge thereof adjacent saidjfloor', with a resilient rubber vsealing strip having a web adapted to be received in Asait groove, a lateral flange on said webandagroove'in the bottorn of said strip, and initially plastic sealing'compouiid, including asphalt as ,a'jcori stituent, in said latter groove, whereby said sealing compound is distributed Vbetween wiLLiAivi vit oiLLins-v e Sti said floor andstripwhen said wallboard is vpressed against said floor.
